1. A method comprising:
- installing second communication interfaces in chassis of first process controllers of an industrial process control and automation system without removing first communication interfaces already installed in the chassis of the first process controllers, the first process controllers configured to communicate over a first supervisory network using the first communication interfaces, the second communication interfaces configured to communicate over a second supervisory network of a different type; and
migrating the first process controllers to second process controllers of a different type while maintaining control over an industrial process being controlled by the first process controllers, the second process controllers configured to communicate over the second supervisory network.

Abstract
A method includes installing new communication interfaces in first process controllers of an industrial process control and automation system. The first process controllers are configured to communicate over a first supervisory network, and the communication interfaces are configured to communicate over a second supervisory network of a different type. The method also includes migrating the first process controllers to second process controllers of a different type while maintaining control over an industrial process being controlled by the first process controllers. The second process controllers are configured to communicate over the second supervisory network.

21. A method comprising:
-
controlling an industrial process using first process controllers of an industrial process control and automation system, each of the first process controllers comprising a first communication interface for communicating over a first supervisory network and a second communication interface for communicating over a second supervisory network of a different type; installing a direct-connected operator station configured to communicate directly with the first process controllers; replacing a secondary one of the first process controllers with a primary one of multiple second process controllers; operating the primary one of the second process controllers using at least a primary server while operating a primary one of the first process controllers using the direct-connected operator station; and replacing the primary one of the first process controllers with a secondary one of the second process controllers; wherein the first process controllers are replaced with the second process controllers while maintaining control over the industrial process.
